as a non-USAian, can someone explain why mail-in rebates were so much of a thing in your country? what were companies getting out of paying each individual upwards of USD$30 on an electronics product in the 2000s, their personal information? and nowadays you give it out for free? am i missing something?
@mavica_again I don't know but my first thought is price discrimination - the people who care enough to send the form are likely the same ones who are price-sensitive enough to make the discount worth it for the company.
